When a preset data (unit price and associated department) of an EAN item is changed at a satellite or the
master using the price change function, its PLU/EAN main file or dynamic EAN file is updated with the new
data. Immediately after this, the new data is automatically distributed to all other machines to update their
PLU/EAN main files or dynamic EAN files which contain the same EAN code. The updated file varies
depending on dynamic file setting for the IRC system.
The EAN data changed at a satellite is also stored in its T-LOG buffer and collected through T-LOG polling
by the master to update its PLU/EAN main file or dynamic EAN file in case the updated EAN data at the
satellite is not automatically distributed to the master due to dynamic file setting for the IRC system.
For further information on the price change function, see the UP-3500 instruction manual.
For the data flow, see the following figures.
• In case that the price is changed at the master:
• In case that the price is changed at a satellite:
If a transmission error occurs during automatic distribution of updated data to other machines after a
price is changed using the price change function at a machine, the machine number of the terminal
which causes the error and the type of error are printed out at the sending machine. In this case, the
system retry function can be used if it is enabled. (For the system retry function, see pages 55–56.)
